“We'll do what we can to accommodate lawful assemblies. I think we’ve have a darn good track record doing that. I think we’ve struck an appropriate balance, but once they overstep the line and decide to disrupt other people’s events. Then they have to be arrested if they refuse to comply, and they refused to comply,” Milwaukee Police Chief Ed Flynn said.

Protesters were trying to drown out the Lincoln Center of the Arts Choir.

“This is not a time of celebration. This is a time of grief and mourning, and business as usual cannot continue in Milwaukee. Because of the way that the police have been allowed to treat people of color, people in poverty, the way they interact with the citizens,” All Peoples Church Pastor Steve Jerbi said.

The group said it won't stop.

Milwaukee police said six people - 5 men and 1 woman - were arrested on charges of state disorderly conduct.

"Jail's not going to scare us," Nate Hamilton said.

"They've been wanting to arrest him (Nate) ever since we started to protest. They've been waiting to do so," Nate Hamilton's mother, Maria Hamilton, said.

Hamilton was released around 7 a.m. Friday. He declined comment to WISN 12 News. By 9 a.m., all protesters had been released from jail.

MPD said charges are being referred to the Milwaukee County District Attorney's Office for review.
